LIQUID-MEASURING`ATTACHMENT FOR TANKS.

Application led vApril 6, 1925. Serial No. 21,032.

My invention relates to and hasy for its purpose the provision of anextremely simple, inexpensive and durable attachment for gasoline storage tanks and similar subterranean tanks by which the yamount of liquid in a tank can be determined `'from a point above the ground and without the necessity of lowering measuring rods or similar devices into the tank as is now the present i@ practice. l" v lt is also a purpose of my invention to provide a liquid measuring device which is adaptable to storage tanks of conventional construction and without in any way modi- 15 ying the construction of such tanks.

ll will describe only one form of liquid measuring attachment for tanks embodying my invention, and will then point out the novel features thereofi'in claims. 2@ 1n the accompanying drawings:

Figure is a view 'showing in vertical section one form of measuring attachment embodying my invention in applied position to a conventional storage tank.

Se Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

`Figure 3 is a plan view of the attachment show-n in' the preceding views. o

Referring specifically to the drawings, in

3@ which similar reference characters referto similar parts in each of the views, my in vention in its present embodiment comprises a pipe 15 of suitable length and diameter so as to extend upwardly from a subas terranean tank 16 to the surace of the ground, such pipe being rigidly connected to the tank through the medium, of an attaching collar 17 provided with a flange 18, through which bolts 19 extend for rigidly ne securing the collar to the tank and into surrounding relation. to an opening 20. The lower end of the pipe 15 is threadedly oonnected to the collar 17, while the upper end of the pi e which projects above the ground is threa ed exteriorly to receive-a connectsleeve 21, the latter in turn being interiorly threaded 'to receive a cap comprising an annular body 22- having a ange23 to which is secured a ring 24 by means of 50 screws 25, for securing a transparent disc 26 in, closing relation to the top of the cap.

.It isto be noted thatthe flange 23 is formed with an annularly depressed portion 23a so that when the ring 21 is secured in place an annular .groove isprovided in which the disk 26 is snugly received.

The body 22 is formed with openings in which the opposite ends of an axle 27 are mounted, a flanged pulley 28 being rotatable upon the axle 27`and being maintained centrally ers 29. A flexible metal tape 30 is trained around the-pulley 28, the flanges of the pull ley preventing accidental displacement of the tape from the pulley and the two stretches of tape depending and extending downwardly through the from the pulley .60 of the axleby means of spacing wash-v pipe 15, with the end of one stretch provided with a weight 31 which counterbalanees a float 32 secured to the lower end of the other stretch of the tape. This float 32 is of elongated form as is clearly shown in Figure 1 and is provided at its lower end with a weight 33by which the iioat is maintained at all times in upri ht position.

As illustrated in *igure 3, one surface of the tape 30 for the purpose of indicating the number of gallons of liquid contained in the tank 16,-

and which calibrations are readily viewed. through the transparent plate 26. In practice, the measuring lattachment is capable of being applied to the pipe 15 after the tank has been tape, weights and ioat being lowered through tliepipe so that the float is partly submerged in the liquid andfmaintained in upright position by means of the weight 33. As the vertical position of the ioat varies in accordance with the `level of the liquid contained in the tank, it will be clear that the tape 30 is moved with and by the iioat so that that calibration disposed uppermost `on the pulley 28 will accurately indicate the number of gallons of liquid contained in the tank.

is calibrated as indicated at 34 placed in the ground, the f As the entire measuring device is support- 4 ed on the cap previously described it will be manifest that the entire device can be removed .from the pipe 15 and through the latter, the weight33 operating to maintain the float 32 in a'position within the tank directly beneath the pipe 15 so that the proper operation of the sured as well as permitting'the removal of the Hoat from the tank to removep the device for any purpose such as the introduction of liquid into the tank when it is desired device is at all times in- I through the pipe, should it be impossible y for any reason to use the ordinary'lling pipe (not shown) to discharge liquid into the tank. n Although l have herein shown and described only one form of liquid measuring attachment for tanks embodying my invention, it is to be understood that various changes yand modilications may be made therein without departing from the spirit of the invention andthe spirit and scope l of the appended Claims.

ley rotatably mounted in the cap, a cali-` mageos brated tape trained about the pulley and eX- tending downwardly into the pipe, a weight on one end of the tape, and a weighted float on the opposite end of the tape.

Q. A liquid measuring device of the character described comprising a pipe, a sleeve threaded on the upper end of the pipe, a cap threaded on the sleeve and provided at its upper end with a flange formed with an annular' depression, a pulley rotatably mounted in the cap, a calibrated tape trained about the pulley and extending downwardly into the pipe, a weight on one end of the tape, a weighted float on the opposite end of the tape, a ring secured to the flange, and a transparent disk fitted in said depression and closing said cap and confined therein by i said ring.
